Solution for 5k^2/24-70k/36 equation: 


k in (-oo:+oo)

(5*k^2)/24-((70*k)/36) = 0

(5*k^2)/24+(-35/18)*k = 0

5/24*k^2-35/18*k = 0

DELTA = (-35/18)^2-(0*5/24*4)

DELTA = 1225/324

DELTA > 0

k = ((1225/324)^(1/2)+35/18)/(5/24*2) or k = (35/18-(1225/324)^(1/2))/(5/24*2)

k = 28/3 or k = 0

k in { 0, 28/3 }
